We studied the seasonal variation of ichtyofauna on two reefs: a stony coral reef and an octocoral (soft coral) reef. Monthly visual censuses were implemented based on transects of 40 x 2 m (80 m2) placed in each ecosystem. The results indicate correlation patterns between annual changes in the fish community and the physical seasonal parameters. Such patterns occur principally within the soft coral reef, where the species richness and relative abundance are greatest during the months of upwelling. The observed groups of the pelagic species Sardinella aurita and Decapterus punctatus are responsible for the decreased diversity during the upwelling peaks. In the stony coral reef, species richness was positively correlated with visibility and ...
